Bug description:
[IMPACT]
hwclock reports incrorect status in audit message
hwclock calls audit_log_user_message(3) to create an audit entry.
audit_log_user_message(3) result 1 is "success" and 0 is
"failed", hwclock use standard EXIT_{SUCCESS,FAILURE} macros with reverse
status. Thus reports it's status incorrectly in audit message.
It is a requirement for Common Criteria Certification that hwclock
reports correct status in audit message.
This has been fixed upstream in https://github.com/karelzak/util-
linux/commit/189edf1fe501ea39b35911337eab1740888fae7a
[TEST]
Steps to test:
1. Install auditd
2. Run following testcase,
# hwclock
2020-03-02 15:03:03.280351+0000
# hwclock --set --date "1/1/2000 00:00:00"
# echo $?
0
# hwclock
2000-01-01 00:00:05.413924+0000
# hwclock --utc --systohc
# echo $?
0
# hwclock
2020-03-02 15:07:00.264331+0000
Following audit messages from /var/log/audit/audit.log,
type=USYS_CONFIG msg=audit(1583161562.884:105): pid=2084 uid=0 auid=1000
ses=1 msg='op=change-system-time exe="/sbin/hwclock" hostname=bionic-fips
addr=? terminal=pts/0 res=failed'
type=USYS_CONFIG msg=audit(1583161614.497:106): pid=2103 uid=0 auid=1000
ses=1 msg='op=change-system-time exe="/sbin/hwclock" hostname=bionic-fips
addr=? terminal=pts/0 res=failed'
Note that last entry in each audit record produced when hardware clock
was modified has, "res=failed". Although, testcase shows no failure
occurred.
[Regression Potential]
There should not be any regression to fix the status given to auditd.
